Mr. Aphiwit Sawad-wuthichaikun, General Manager Tesla Engineering,

represents Tesla Engineering in donating 200 bags of cement for temple construction

at Bang Yang Temple, Ban Pong District, Ratchaburi Province.

The temple needs restoration after having been constructed for 80 years.

The people in the community around the temple help out with the construction.

Maintaining Thai traditions and caring for the society and environment

Mr. Aphiwit Sawad-wuthichaikun, General Manager, and staff of Tesla Engineering
contribute to a Kathin (alms-giving) ceremony to uphold Buddhism
at Phra Baht Khao Makham Monk Sanctuary, Makham Sub-district, Makham District, Chanthaburi Province.

The alms from this Kathin Ceremony were used for restoration of a storage house, monk living quarters, and monk lavatories.

“Kathin” is an important Buddhist tradition where Buddhists organise an alm-giving ceremony within 1 month after the Buddhist Lent period is over (Ok Phansa Day). The event not only upholds Buddhism and Thai tradition, but also gathers people in the community to creating bonding and unity.

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

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.

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 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.

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

     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

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

   Ground subsidence can be caused by many factors. This technology can take into account all of these factors and ensure that the repair is effective which is worth a long-term investment.

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.

The procedures for lifting-relevelling the delivery parking area

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.

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

Injection of polyurethane to fix warehouse subsidence

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

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
