It's also a good idea to check the surrounding landscape. Proper grading around the house guarantees water flows away from the foundation. By combining effective drainage installation with diligent drainage maintenance, we create a robust defense against water infiltration, protecting our walls and foundation from moisture-related issues.

Crack Injections

When it comes to repairing cracks in walls, crack injections are an effective and long-lasting solution. They provide a robust method for sealing cracks, preventing water infiltration, and maintaining structural integrity. Understanding the different crack types is essential for selecting the right injection techniques.

First, let's identify the main crack types we might encounter:

Hairline Cracks: These are very fine and often a result of shrinkage.
Structural Cracks: These indicate significant movement or settling.
Non-Structural Cracks: These usually result from temperature changes and other external factors.

Choosing the appropriate injection techniques depends on the type of crack we're dealing with. For hairline cracks, low-viscosity epoxy is often used because it can penetrate deep into the finest cracks, ensuring a thorough seal. For structural cracks, high-strength polyurethane is preferred due to its flexibility and durability, which can accommodate slight movements in the wall. Non-structural cracks might be addressed with hydrophobic polyurethane, which expands upon contact with water, effectively sealing the crack and preventing further water ingress.

Waterproof Plaster

Waterproof plaster is a versatile and practical solution for enhancing the durability of walls against moisture. By applying this specialized plaster, we can protect our walls from water damage, mold growth, and structural deterioration.
