Overview of main products and technologies

1. Geotechnical survey (Swedish weight sounding test)
 It is a survey method commonly used for checking the strength of the ground for building houses on. The strength of the ground is surveyed by adding a load of up to 1 kN (100 kg) to the head of the rod with the screw point attached to measure the penetration depth, and rotation is applied when the penetration stops and the number of half turns required to screw in 25 cm is measured. The surveying equipment has excellent maneuverability, so measurements can be conducted without any issues even in narrow areas.
2. Boring survey (standard penetration test)
　By boring into the ground and making a hole, we can check the composition of the ground, collect samples for testing soil quality, and perform standard penetration testing, in-hole load testing. Standard penetration test is a type of sounding test performed inside the hole. Generally, the strength of the ground is surveyed by attaching the standard penetration test sampler to the tip of a rod for each meter of depth, lowering it to the bottom of the boring hole dug to the measurement depth, letting a 63.5 kg weight drop by free fall from a height of 75 vm, and then measuring the number of drops required for the weight to penetrate 30 cm into the ground.

Message from the representative

Please trust Suiken for ground that supports houses.
In addition, we propose and conduct effective surface improvement work at a comparatively shallow depth, steel pipe pile construction work involving the driving of steel piles as far as the solid layer, and necessary ground reinforcement work, for instance, using the Res-P construction method.
