Checking And Repairing Your Home’s Foundation

You should address the problem immediately if you notice your home’s foundation is crumbling. Looking after your home and your investment is important, and the following tips can help you know what to do and who to contact.

Why should you take immediate action if you notice you have a crumbling foundation?

The entire stability and safety of your home can be compromised if the foundation is crumbling, as it is literally the base on which your home sits. Proper foundation repair can fix the problem, and the earlier you take steps to address it, the more chance there is of fully repairing your foundation. And preserving your foundation’s structural integrity can help prevent any issues in the future.

Crumbling

Various materials typically comprise today’s concrete foundation, and the particles can weaken over time, often because of humidity. Once this happens, the foundation begins to deteriorate, leading to potentially serious issues and the need for foundation repairs once its stability is compromised.

Signs to indicate your foundation is crumbling

These early warning signs shouldn’t be ignored; it’s always better to carry out any foundation repairs sooner rather than later.

  • Your foundation has cracks in it
  • Loose white powder on your foundation
  • Basement has a high humidity level
  • Loose pieces of concrete falling off
  • Brittle concrete blocks
  • Bricks and other exterior cladding with large cracks
  • Foundation has bubbles appearing

A crumbling foundation can put your home at serious risk:

You and your family can be at risk if your foundation is beginning to crumble, as it can potentially affect your home’s stability and safety. A deteriorating foundation may even cause a home to be condemned. And of course, it can lower the value of your home too; buyers won’t look at a house with a crumbling foundation.

Causes of a crumbling foundation

1) Year the house was built

Concrete of poor quality was used a lot to build homes during the 1920s when concrete was mixed with different materials found on the construction site. Major problems with crumbling are now all too common in houses built during that time, and many homeowners have incurred costly foundation repairs or have had to replace the foundation altogether. Stricter rules have been put in place for newer home construction, and the addition of reinforcing steel rods has also meant more stability.

2) The area where the house is located

Foundation damage is more likely in a home that has been built on wet soil rather than dry sandy soil, and your geographical area and the local geology can affect your foundation.

3) Urban development

A house located next to a busy road is more likely to experience crumbling concrete; the frost is more likely to crumble and affect the foundation if frost is common in that area.

4) Humidity

Decomposition can occur in concrete over years when the minerals present are pushed out by high levels of humidity.

Preventing concrete foundations from crumbling

Asking an expert to look at your foundation for any problems and recommend any foundation repair should be your first step if you suspect you have foundation problems. Knowing how to address the issue and how it might affect your home in the future can help you to make the best decision when it comes to having repairs carried out.

Repairing your concrete foundation

Foundation repairs Edmonton consist largely of what is known as resurfacing, which means applying a new coat of concrete to any damaged areas after first getting rid of all the crumbling pieces. This is the most affordable option, and it can help to make your foundation and the rest of your home safe and stable again. It’s also an effective long term solution, meaning that you shouldn’t have to worry about foundation repairs for some time. Formwork connecting to the rest of the foundation is the method used if only part of the foundation has been compromised. If your home sits on a corner that is often frost covered or sits on a negative slope, this option for foundation repair may be called for.

Replacing the foundation

Major problems which put your entire home at risk mean the foundation has to be replaced, a procedure that involves putting in a new foundation once your home has been lifted or moved from its existing one. You’ll need the expertise of a foundation expert to do this, and the procedure is a lot more costly, although your new foundation will be up to code.

Check your foundation regularly

If you notice any signs of crumbling, have your foundation checked, although it should be checked regularly anyway for signs of damage. Protecting your investment is important, as well as knowing you and your family are safe and your foundation should be inspected before any home renovations or refits are carried out.

Should You Go For Spot Or Extensive Foundation Repairs?

You have spotted a leak in your basement, and you are worried now. You are rightly concerned about the condition of your house’s foundation. A small leak or crack can be a sign of a big developing problem. It may be the obvious sign of underlying extensive damage. Should you call a contractor for the foundation repairs?

Most homeowners ignore a small leak because they worry about the high cost of an exterior waterproofing project. Should you repair the leaking spot immediately?

The type of repair needed to fix such a leak depends on many factors. Most homeowners lack the skills and knowledge to ascertain what type of solution is best to fix such a leak. There are two

solutions to repair a leaking spot near the foundation. The first is the spot repair, and the second is an extensive foundation repair. A spot repair is not a small project as the term implies. Even this type of repair involves excavating the foundation and reaching the leaking spot from the foundation wall’s other side. A professional foundation contractor never advises patching up a small leaking spot to stop the leakage. It is a temporary solution that never solves the main problem.

Fixing a foundation leakage is not the same as fixing a roof leakage. There is a possibility there are more leaks and cracks near the leaking spot. The affected spot requires proper inspection, excavation, and repair. Once the water has seeped into the wall, it starts weakening the building materials. The concrete and bricks used to build the wall are not completely impervious to water. Once the water seeps into the wall from one spot, it will easily spread to other parts of the wall. If you inspect around the leaking spot, you may find many other leaks. This is the reason you should go for proper foundation repairs and not gamble with a spot repair. An extensive repair is a permanent solution that ensures long term strength  and safety of your house structure.

Your first step should be to remove the dirt near the outside wall. Inspect the exposed exterior side of the foundation. The wet side of it will reveal the root cause of the leak. The leakage may be due to pressure from a water source or supply system. It shows the foundation is under pressure and stress.

For the spot repair, a trench measuring 8 x 10 feet is dug down to the level of the footings. Once this is done, the contractor has to inspect several things to find the root cause of the leakage.

1. Is the foundation defective? Is there a hole or crack? Is the foundation under pressure from large rocks or tree roots?

If any of these factors are responsible for the foundation damage, you are on the right course of action. Just fix the root cause and repair the defective part of the foundation. Do not forget to apply a foundation coating and replacing the dimpled membrane. More and deeper excavation may be needed depending on the extent of the damage.

2. Inspect the weeping tile at the trench bottom. Is it crushed or earth clogging it? Or is there no weeping tile at all? The culprit may be the roots of a nearby tree.

This is the right time to inspect the tile condition. If it looks in good condition and only one spot is damaged due to leakage, then you can relax. A simple and inexpensive spot repair is sufficient to fix this problem. Once the foundation repairs are completed, you are done with it. However, if the damage extends to the weeping tile, then extensive repair is required. This type of repair will involve entire weeping system replacement. You may have to install an additional weeping line that ends up at the French drain.

3. Does the weeping tile have sufficient gravel around it?

Is the gravel choked by earth and the voids around the gravel are filled? It is difficult to ensure enough 3/4-inch gravel around the weepers. A landscape fabric is wrapped around to prevent the earth from choking the gravel.

4. You should check the soil condition around your home. Is it topsoil and sand base or mostly clay?

It is an important thing to check. You can be assured of good drainage if the soil is made up of black earth with a sand base. In case it is mainly clay, you can be sure some substance that cannot absorb water is pressing the water against the house foundation.

The leak problem, in this case, will not be solved by a spot repair because the groundwater that has seeped into the foundation is going to find another weak point and come out through that spot. The groundwater pressure can be somewhat eased with the help of spot repair by placing a good amount of gravel in that area. The air pockets of the gravel will be filled by the water, and it will ease the pressure in that area. Any measure is better than not doing anything when the clay surrounds the foundation.

5. The condition and age of the waterproofing treatment are the other factors that affect if you need foundation repairs.

You will not find any such treatment if the house is about 100 years old. You will find terracotta weeping tile and parge coating in houses that are about 50 years old. Most likely, it has stopped working properly and should be replaced with the latest standard feature — a flexible weeping tile that has a fabric sock. It is surrounded by gravel, and a dimpled membrane protects the coated wall and footings.

As you can see, spot foundation repairs can work in certain conditions. However, it is not a substitute for the proper, permanent, and complete repair of the foundation. Discuss all these factors with your foundation contractor to determine if a spot repair will solve the problem, or it is time to go for extensive excavation and repair of the foundation. Fix a small leak as soon as possible before it becomes a bigger problem that will require more expensive foundation repairs.

Everything about foundation repair

The point of a foundation is to provide stability to the structure. The weight of the house sits on the foundation, which sits on the ground. 

There are a number of different kinds of foundations. Most of them extend below the ground, and the large the building, usually, the deeper the foundation reaches. Slab Foundations are rather common, and mostly consist of a hole the size of the house dug directly below the house and filled with concrete (this is of course, a very simple explanation, there is more to it, but that is the basic idea.)

There are a number of dangers to a foundation, but the two most common are shifting soil and uneven support. Underground rivers can move the soil under your building, which then will put stress on the foundation. Another common damaging factor is the amount of water in the soil. In areas where there is regular, heavy rainfall, followed by a dry season (like, for instance, much of the southwestern USA) the soil tends to be a little unpredictable. Moisture seeping into the soil will cause it to expand, and moisture leaving will cause contraction.

When soil freezes and thaws it also tends to expand and contract. The removal of deep soil will affect the freezing and of this soil, in come cases, so there are often freezing units put into the foundations of such large buildings in areas where it’s cold almost year round.

More about foundation repair:

Stone foundations can crack for several reasons
Stone foundations are not used very much in the construction of homes or buildings today. However, there are several old homes and buildings were these structures still existent.

About foundations and the frost line
In geological terms, the frost-line is the lowest point at which soil freezes during the winter. (often around between 5 and 8 feet or 1 and a half to 2 and a half meters.)

What to do when hiring a contractor 
After you contact a contractor, the first thing he or she should do, is visit your home and examine the extent of damage to your foundations. The estimate they present you should be based on their inspection. Most contractors do not charge for estimates. You should acquire at least three estimates.
