TECHFLOW GROUT GP

Bostik Techflow Grout GP is a general purpose, non-shrink cementitious grout built with dual expansion technology that compensates for shrinkage in both the plastic and hardened state. It's a pre-mixed, just-add-water grout used for bedding base plates, anchor bolts, bars, fittings, and crane rails, and can be mixed to a stiff, plastic, flowable, or fluid consistency to suit the method of placement, whether that's pumping, trowelling, ramming, or pouring.
It's suited to a wide range of precision grouting jobs from machine base plates to structural anchoring, on sites where reliability under load matters. Its lower water to cement ratio cuts drying shrinkage and permeability while boosting durability, and because it contains no metallic iron content, so there's no risk of rust staining coming through the finished grout.

Why choose Techflow Grout GP?
Techflow Grout GP is low VOC, making it a clean, low-impact grout to work with on site. Its dual expansion system is tested to ASTM C940, so shrinkage is compensated for from the moment it's placed right through to full hardening. Depending on the consistency mixed, it develops 28-day compressive strength of 40 to 85 MPa, giving specifiers a wide performance range from a single product. It also carries no metallic iron content, so there's no staining risk over time. Techflow Grout GP is made in Australia by Bostik and tested to AS 1478.2, AS/NZS 2350.11, and the relevant ASTM standards for consistency, set time, and expansion.

Where to use it
Techflow Grout GP is used on clean, sound concrete substrates that have been mechanically abraded to remove laitance, for bedding base plates, anchor bolts, bars, fittings, and crane rails at thicknesses from 10mm to 140mm. 

TIP: When the job calls for a fast return to service rather than the widest strength range, reach for Techflow Grout HES. It hits usable strength within 2 hours, while GP remains the more versatile, everyday choice for general precision grouting.
