Fix Open Cracked Concrete Base

In Poured Concrete

Cracks in the poured concrete foundation are predominant with horizontal or vertical walls, and homeowners with the type of problem would experience seepage of water through one entry point – pipe penetration.

A resin-based mortar such as epoxies, polyester, and polyurethane are used to repair concrete cracks. Their excellent bond characteristics, very low shrinkage, and good dimensional stability during curing make them the adequately durable material for this problem. But, it’s important to note that the materials and methods used for repairing cracks in concrete depend on the location and size of the crack.

For instance, a small split with less than .25inches wide, require the use of gray-tinted concrete caulk for a quick fix, and if you need a more permanent solution, a pourable crack filler or fortified patching cement is the way to go. Request for a free estimate or call 780 707 9535 today.

Best Approaches & Tips For Preparing Cracked Concrete For Repair

✓ Surface Prep - Clean loose material

As a professional, we clean loose material from the crack using a wire brush, or a portable drill with a wire wheel attachment. Debris or lose materials left while fixing cracks can result in an incoherent bond and ineffective repair and even cause yet another stealthy leakage. Prepare concrete by shot-blasting, acid etching, or diamond grinding and follow by mixing.

✓ Chisel out

We chisel out the crack to enable us to create a backward-angled cut which is wider at the base than at the surface with the aid of chisel and hammer. Kwaja foundation crack repair contractors understand thorough preparation of the cracked surface is essential for creating a good bonding surface to stand any harsh weather.

✓ Prepare for Foundation repair

Preparation of the crack surface before repairing it is essential and we do this by applying a thin layer of latex bonding agent to the entire affected area, using a paintbrush. The latex bonding agent is a crucial element in this phase that helps keep the repair material from loosening or popping out of the crack.

For minor patches and cracks up to 0.75 inches wide and 0.5 inches deep, we use an epoxy ratio of 3 parts of silica to 1 part of the mixed epoxy volume. If your crack is major and the patches and cracks greater than 0.75 inches wide and 0.5 inches deep, we use an epoxy ratio of 4 parts of silica to 1 part of the mixed epoxy.

Recommended Steps to Repair Foundation Crack

Sealing split or wall chasm depend on the stability of the fissures your home has.

✓ Determine the stability of the crack

Our specialist determines if a foundation crack is stable or not. Building walls with stable cracks require frequent monitoring, sometimes for several months. Mark is drawn as an indicator to track the length as well as its width at the widest gaps.

✓ Repair with Mix Hydraulic cement

We fill crack with expanding insulating foam working from bottom to top. Cement is applied in layers until the patch is slightly higher than the surrounding area. The materials used are resistance to shrinkage cracking and abrasion.

Frequently Asked Questions

✓ Do Cracked Foundation Need Urgent Repair ?

Yes, although tiny cracks or a little shift might not necessarily require a quick fix. However, you will need to pay attention to some fracture processes that may develop over time, such as crack branching, microcracking, etc..

✓ How do you fix a cracked Wall ?

You will need a resin-based mortars such as epoxies, polyesters and polyurethanes to patch your cracks. If you are to fix this yourself, ensure to look for high-bond strength and concrete material with high resistance to abrasion, high compressive, tensile and flexural strength compared with cement mortal and concrete.

✓ When should I Be Worried about Renovation?

The shift in the building structure, entrance doors failing to latch during weather transitioning, micro-cracks in the walls, and difficulty in opening and closing of windows. These indications are among the few things you consider.

✓ What is the cost of fixing foundation Crack?

The cost of repairing vary depending on the type of foundation cracks ( shrinkage, non-structural, hairline, stair-step, or foundation slab). The worst type of crack is the stair-step and fixing may cost at least $4000, and to fix the common which entails sealing up with epoxy and polyurethane crack injections may cost you between $650 and $3000.
