Fix subsided homes and garages, and fill voids
The subsidence rate in Thailand is high. The causes are over-pumping of groundwater, heavy construction load, vibration from traffic, etc. Subsidence of soil highly affects the residential area, causing problems that many of us are facing such as sunken homes, sunken garages, and unlevelled home extensions.
Fixing the subsiding ground is a matter to carry out immediately.
Tesla Engineering understands the problem and has the solution that is non-invasive, fast, and minimises disturbance on your daily life, by using Polyurethane Injection Technology, an imported innovation from the US.

Characteristics of polyurethane
Polyurethane injection technology has been researched and developed to withstand loads as high as 50 tons and expands as much as 20 times. The material permeates the voids between the soil and combines with the subsurface material. Its expansion can lift sunken floors, roads, and factory grounds, with the ability to lift existing weights as well as additional loads. A levelling laser ensures accurate and precise results. A team of engineers with experience domestic and abroad oversees the entire operation.
Initial signs of home subsidence
- separation of floors of main house, garage, or home extension
- long cracks appear on walls around the house
- floors or walls tilt at visible angles
- noticeable separation of beams and walls
- soil subsidence leaving gaps and holes around the house
Home subsidence repair by polyurethane injection
The polyurethane injection technology has been researched and developed to withstand extreme loads while expanding with accurate dimensions. The technology has also been advanced further for deep subsurface injection in order to stabilize soil layers and strengthen foundations. The technology has been widely used in the US, Europe, Oceania, and Asia for more than 40 years.
Advantages of this method
- Silent, no noises to disturb family members or neighbours
- No mess, no concrete dust, water, or anything to clean up
- Fast and convenient, repairs are finished within 1 day
- Safe for human and pets, zero negative impact on the environment
HOW IT WORKS
Drill 16-mm holes every 1.5 meters for injecting PU Foam to lift sunken floor
Drill 16-mm holes every 1.5 meters for injecting PU Foam to lift sunken floor
Inject highly expandable PU Foam into subsurface under the concrete. Check structural movement with 0.5 mm accuracy while the ground is being lifted.

SLAB LIFTING
Polyurethane concrete lifting uses a high-density foam material that is injected under the slab. This expanded foam fills any voids beneath the slab and lifts the concrete.
Void filling around the house
fill gaps under or around the house
Many face problems with gaps around the house caused by soil subsidence. Sunken ground usually occurs after heavy rain or flooding. These gaps can be very problematic for house owners.
Why fill the voids?
- avoid accumulation of waste under the building
- ward off inhabitation of venomous or disease-transmitting animals
- prevent development of infestation transported from rain, subsurface water, and wastewater
Strengthen weak grounds to deter subsidence
SOIL IMPROVEMENT
The foundation of engineering structures is the part that bears the weight of the entire constructionOften, spread footings are constructed without testing the soil bearing capacity or without considering subsurface water, resulting in subsidence, tilting of structures and cracks in walls, which can become very dangerous.
