Fix gaps around subsided house by polyurethane injection
Main causes of gaps around the house
Gaps can result from poor compaction of the soil or from insufficient settling time for the filled soil. These gaps appear and become more severe when the ground sinks below the beam. In Thailand, many of these cases occur especially in the rainy season or when the area is flooded.
Problems from the presence of gaps
- Venomous or disease-transmitting animals may inhabit the area. Pets may also choose to hide under the house.
- Waste may accumulate under the building
- Rain, subsurface water, and wastewater may collect in the area and develop infestation
Initial solution for fixing the gap
The problem can be temporarily fixed by placing bricks or plants around the gaps. However, the ground may still continue to sink.
Fixing gaps by polyurethane injection
Tesla Engineering provides an effective solution for fixing gaps around your house by using the polyurethane injection technology. This technology works very well due to the ability of the material to expand as much as 10-20 times which can fill the gap completely, giving you a peace of mind for any problems that might occur from the presence of gaps.
Steps for filling the gaps using polyurethane
- Install an unobtrusive 12-mm diameter aluminium pipe into the ground spaced 1.0-1.5 meters apart depending on the size of the gap
- Inject polyurethane into the pipe. The material will expand and rapidly fill the gap completely.
- After the gaps are completely filled, the excess material will be removed and the area cleaned up with no hassle for home owners.
Fix sunken road prevent ponding
The trouble with ponding on roads can be seen often during rainy season. Many times it is a result of heavy trucks causing the road to sink.
The solution to sunken roads and ponding is PU injection which can lift-relevel the road and drain the water.
Steps to fix ponding
1. Staff conduct an initial investigation of the site
2. Drill a 16-mm hole through the concrete surface
3. Inject PU to fill the voids and lift the surface
4. Plug the drill hole with quick drying cement to prevent water seepage

Lift-relevel factory floor, Rayong province
Large shelves in the warehouse produces a heavy load on the ground causing it to sink. Tesla Engineering uses the polyurethane injection technology to fix this problem by injecting the chemical material into the soil, causing it to compact and lift up until relevelled without any demolition or relocation of the shelves.

Fix sunken factory road surface in Rayong
Due heavy trucks constantly transporting through the area, the road surface sunk in 5 locations. Tesla Engineering used the polyurethane injection technology to fill the voids under the concrete and lift the surface to its original level. The process is fast and does not require demolition.
Strengthen ground under machinery, Nakhon Ratchasima province
Vibration of the machinery was caused by voids and loose soil under the concrete which can lead to ground subsidence. Tesla Engineering provided an effective solution using the polyurethane injection technology to strengthen the soil without moving the machinery. This solution is fast, economic, and guaranteed.

Stop leakage for underground parking area, Ayutthaya province
An underground parking area of a mall in Ayutthaya province had a problem of water leaking from the under the concrete floor. Tesla Engineering provided an effective solution by injecting resin to fill the gap and preventing leakage. This process is fast and economic.
Fix sunken warehouse floor, Rayong province
A warehouse in Rayong subsided due to poor compaction of soil before construction as well as due to the heavy load from merchandise storage. Tesla Engineering provided an effective solution by using the polyurethane injection technology to lift and relevel the sunken floor without demolition or disruption of the warehouse operation.
Lift subsided concrete road, Chonburi province
The entryway of a factory in Chonburi subsided due to heavy trucks passing in and out the entire day. Tesla Engineering provided an effective solution by using the polyurethane technology to lift and relevel the concrete road surface.
