The foundation of this house absolutely had to be repaired since there was water infiltration. A mini excavation was carried out and there were challenges that surfaced. Very solid rock to prevent the excavation of a section. We had to use a concrete saw, make cuts to weaken the obstacle and use a hydraulic hammer. It was a much longer process than a simple excavation.
Cracks to be repaired
Foundation cracks required repair to prevent expansion. Cutting and cleaning were carried out before plugging the cracks with concrete.
Waterproofing
An elastomer membrane has been installed throughout the excavated section. This allows the foundation and joint to completely waterproof between the flooring and the sole. Then we installed a draining membrane. Its role is to protect the first membrane and allow an efficient flow of water to the drainage system.
French Drain
We installed a French drain on 2 sides of the house to remove any water that divers this section of the foundation. A high-quality BNQ drain has been installed to ensure proper flow. Here are the steps:
- Excavation
- Upgrading the bottom of the trench
- Laying the French drain
- 3/4 net stone setting
- Installing a geotextile.
