A precision grout is a liquid mortar. The main function of a precision grout is the effective transfer of load from the structure or machine to the foundation. In order to enable this, the grout must provide adequate permanent bearing, be non-shrink and have sufficient strength to resist any loading imposed upon it. TO get the grout into place, often into small gaps or confined areas, the grout must be sufficiently fluid so it can flow or be pumped. Cement based grouts can be used for many applications but resin-based grouts are preferred in critical situations especially where dynamic loads are expected.
