The correct execution and checking of the performance of ties anchored in soil or bolts are very important for the quality assurance of retaining wall’s projects. The safety factors calculated on the project can only be confirmed after tests that guarantee the resistance of these elements.

The Fountest provides a technical project follow up focusing on the correct execution of these elements – drilling, anchor installation, sheath installation, anchor bond length installation, tensile load application and head execution, with grounding on the standards and geotechnical manuals in effect. We provide or inspect the tests recommended by Brazilian Standard NBR 5629:2006 – Execution of ties anchored in soil.

The execution of bolts, must also be done carefully, despite the non-existence of Brazilian Standards for its control. We prescribe executive methods for drilling, implementation and installation, corrosion protection, sleeves (couplers), injection and head’s protection. We also provide pullout test with specific methodology for different enterprises.
