Exhibition by Tesla Engineering

งานวิศวกรรมแห่งชาติ2562

Tesla Engineering presented an exhibition sharing know-how for repairing sunken floor

using polyurethane injection technology, an innovation from the USA for participants in the National Engineering Day 2019 at Impact, Muang Thong Thani

งานวิศวกรรมแห่งชาติ2562

 

The polyurethane injection technology is a widely used method overseas for more than 40 years. Tesla Engineering introduced this innovation in Thailand and provided services for lifting floors for problem that require minimum repair time, unable to move heavy machinery, or roads that can not be closed off.

 

Floor lifting using polyurethane technology is an effective solution for problems with many repair limitations. The operation requires a minimal working area for drilling a 16-mm hole to inject the chemical material. The PU foam will expand to fill voids and lift concrete surfaces. The height rise is regulated using a levelling laser with a 0.5 mm accuracy. Although the method is highly versatile, it is limited to areas with pile foundations.

งานวิศวกรรมแห่งชาติ 2562

 

Tesla Engineering’s exhibition booth received great interest from the event participants because ground subsidence is a constant problem in some areas of Thailand. The subsidence affects factories, roads, and even household garage floors. Therefore, those who encounter these problems are interested in learning about polyurethane injection, which is an effective solution.

Fill gaps under factory building

Fill gaps caused by subsidence under factory buildings

Factory buildings with problems from subsidence resulting in large gaps

The surrounding area sinks below the beam level resulting in a large void under the concrete. This is not only aesthetically unpleasant; it can also be inhibited by dangerous animals and insects.

โพรงใต้พื้น

Because of the continuation of manufacturing and production processes is necessary, most businesses can not afford to close off the area or shut down their operation in order to repair the gaps.

The polyurethane injection technology is the best solution to this problem because it does not require the area to be closed off completely. Moreover, the effectiveness of the technology is unquestionable since the chemical material can expand as much as 10-20 times, ensuring that all the voids and gaps are completely filled.

Lift-relevel sunken floors Fix sunken warehouse floor

แก้ไขพื้นโกดังทรุด

Lift-relevel and repair sunken floor of warehouse

 Sunken warehouse floor can cause transportation problem

Tesla Engineering presents a new innovation, the Polyurethane Injection Technology, that can effectively repair sunken floors without demolition and reconstruction. Therefore, your transportation operation will not be obstructed during repairs.


    A warehouse functions as a critical point in the production process, by storing goods and merchandise while waiting to be transported to support the production or sales distribution.

    Therefore, these buildings have to be strategically located in an area appropriate for stocking the merchandise, as well as safe and convenient for transportation and distribution

Problems that may affect your business


Unlevelled ground surface caused by subsidence can highly affect the transport of goods. Areas with unlevelled surface can be very hazardous for the operator as well as may damage the merchandise during haulage. If the ground continues to sink, the damage may become extensive and cause long-term problems for the transportation or haulage operation.

     Tesla Engineering provides a highly effective solution to problems with sunken or unlevelled ground. Using the polyurethane injection technology, we can lift and relevel concrete surfaces to enable a smooth transportation and haulage operation, which will minimise the chance of goods becoming damaged

Photos from our past project

The project site is an entryway for a warehouse. The ground sunk after bearing the load of transported merchandise for a long period. The unlevelled floor has become a considerable problem for the haulage operation.


Advantages of polyurethane injection

The injected polyurethane can permeate into the voids and combine with the subsurface material. The expansion of the material can lift surfaces to the desired level. This technology also highlights

Lift-relevel concrete surface for delivery parking area

ซ่อมพื้นทรุดลานจอดรถ

Lift-relevel sunken concrete surface for delivery parking area

A delivery parking area subsided due to excessive delivery vehicle loads driving in and out the entire day. Presence of water under the concrete also added to the cause of subsidence.

พื้นทรุด ลานจอดรถ

Because delivery trucks enter the parking area throughout the entire day, the company can not afford to close off the parking area to be repaired for long periods of time, since it will affect the transportation system and will disrupt the business, therefore, polyurethane injection is the solution to this problem.

Advantages of ground lifting by polyurethane injection

The area does not need to be closed off for long periods of time. Only a certain part of the problematic area is required for the repair operation. Very little time is need for fixing. The area can return to its normal function immediately after the repair operation is completed. Creates zero pollution or dust because there is no demolition or excavation of the concrete.

The procedures for lifting-relevelling the delivery parking area

ซ่อมแซมพื้นทรุดลานจอด
ซ่อมแซมพื้นทรุด
พื้นทรุด ต่างระดับ

The operation starts with closing off part of the parking area. A 16-mm hole is drilled through the concrete. Polyurethane is injected through the drilled hole. The chemical material permeates into the soil and combines with the subsurface material, and then expands to drive out the water underneath the concrete as well as lifts the concrete surface until it reaches the original level. The rise of the concrete surface is regulated by a levelling laser.

After the injection is completed. The hole is filled with non-shrinking grout. The cracks are also filled by applying Pure Epoxy Resin to prevent water seeping through the concrete.

Polyurethane can lift as much as 50 ton/sq.m. and can withstand vibration caused by heavy vehicles. This technique can also extend the life of the concrete floor.

Problem fixed by injecting polyurethane to strengthen soil and lift-relevel the warehouse

ซ่อมพื้นโกดังทรุด

Soil testing under foundation before PU injection

(using a Kenzelstab Penetrometer Test)

A Cone Penetrometer (Kunzelstab) is a tool for testing the density of the soil, which can penetrate as deep as 10 meters. It is used for collecting soil data under the foundation in order to assess the situation. The tool is driven into the soil by releasing a standard 30-kg weight above. Every 20 centimetres, the density (friction) of the soil is evaluated and converted into the bearing capacity that indicates the amount of load the soil can take.

Test results show presence of a void and loose soil as deep as 50 centimeters

Injection of polyurethane to fix warehouse subsidence

ซ่อมพื้นโกดังทรุด

The soil improvement process starts with the injection of polyurethane through a pipe into the problematic soil in order to increase the density and compaction. Finally, injection of polyurethane directly under the foundation will lift-relevel the structure to resemble its original level.

Fill voids and lift-relevel sunken concrete inside the warehouse

ซ่อมพื้นโกดังทรุด

Polyurethane is injected under the concrete floor through 16-mm holes drilled every 1.2 meters. The injected material expands and fills as well as compacts the soil. The expansion force slowly lifts the floor. Throughout the operation, the rise is measured and regulated with a levelling laser. The operation enables the floor to be lifted to the desired level and increases the strength of the foundation.

Advantages of lifting floors by polyurethane injection

  1.  Repairs using less time No need to destroy old floors. Your space can be used within 15 minutes after the injection.
  2. No disruption of your operation No need to move heavy machinery or shelves. Your operation can continue while the floor is being fixed.
  3. Get even floors that can bear more load Even out sunken floors while adding strength to withstand as much as 50 ton/cubic meter.
  4. No problem with cramped space Able to access all areas. The technology features a 90-meter long cable which can reach small and narrow spaces such as underneath stock shelving or machinery
