Significant hollowness noted on Cement flooring.
Entire flooring is significantly hollow. This can lead to cracks in flooring, further deterioration with time will affect the main / mother slab. Sign of water stagnancy also noted at places, causing water seep-in as seen by Infrared image. If not rectified, moisture will spread in adjacent below areas and cause further damage.
We recommend chipping off loose flooring layer till hard surface and laying of new flooring.
