PU Concrete Elevation Device
Material: PVC, PU
Each unit includes: plastic base + PU tube + cylindrical header
Mainly when the floor slab is being constructed, in order to reduce the chance of an uneven concrete surface, a height gauge will be set before grouting the floor slab.
Height: 10 cm ～ 70 cm
※The color of the plastic base depends on the inventory
Before grouting, confirm the benchmark elevation of the concrete surface, and then use a laser to measure and confirm the elevation of the elevation gauge. After confirming that the elevation of the elevation gauge meets the benchmark elevation, cut off the elastic tube and put an indicator head on the elastic tube. During the subsequent grouting operation, control the concrete surface to the lower edge of the small flag to accurately control the flatness of the floor concrete surface.
