SINTEMAR, Foundation repair: Chockfast grout of a reciprocating compressor

During the video, you will observe the initial condition of the foundation of a reciprocating compressor Nuovo Pignone Model 5HF / 4, at the facilities of the company "Soluciones Químicas para el Campo y la Industria" in Minatitlán city (México), with the common problems to be found on an old cementious foundation: cracks, internal contamination with water, chemicals and oil, lack of proper anchoring due to inefficiency of bolts, cold joints and lack of contact with the bottom of the machine. All this was leading to an excessive vibration of the compressor until the point of losing 45% of its effective capacity, limiting production.

The full repair procedure which was recommended by SINTEMAR (www.sintemar.com) can be seen in the video: extraction of anchor bolts, injection of Chockfast Red Liquid epoxy resin at high pressure from the inside of the foundation, achieving the expel from the cracks of residual oil, water or chemicals, filling them with epoxy resin and the recovering the monolithic foundation. Also, all damaged and contaminated concrete is removed until getting finding a solid and healthy foundation where to start restoring the grout.

After eliminating the factors that prevent a good anchoring of the compressor, new bolts were installed and the foundation was restored using the epoxy grout CHOCKFAST Red, ideal for this type of dynamic equipment, as it will keep the alignment indefinitely, and absorb much of the vibrations produced by the reciprocating compressor - given its high coefficient of elasticity - and protecting the concrete below of undesired filtrations.
