It has been brought to our <br /> attention that prior to lifting the structure, and post lift, large cracks were observed and or developed at the <br /> existing concrete foundation in various areas. R&R Foundation Specialists has provided L120 with <br /> additional photos of the locations of the concrete cracks. <br /> Based on the information provided to us and the analysis performed, we recommend the following repairs <br /> at the cracked concrete locations for improved performance/concrete strengthening and limiting of future <br /> crack development/existing crack expansions. <br /> 0. 790 9502 <br />
