Congrout GP is a non shrink cementitious grout designed for grouting applications where it is necessary to eliminate shrinkage whilst completely filling the gap between the substrate and the base plate. Congrout GP was designed for use in local conditions and therefore has extended working times. Congrout GP is a general-purpose grout designed for use in all non-critical applications.

Advantages includes
- Expansion system eliminates shrinkage in plastic state.
- Non Metallic.
- Only requires addition of water.
- Good early and ultimate strength.
- Low permeability.
- Excellent flowability.
- Use for concrete repair work.
- Chloride free.

SURFACE PREPARATION
Surfaces should be clean sound and free from oil, grease, laitance and loose particles. Metal surfaces should also be clean and free of rust, oil, grease and contaminants.
FORM WORK
The formwork should be watertight. Therefore a joint sealant should be used to close all points where forms meet and also around the bottom and top of formwork.
PRE-SOAKING
The prepared areas should be flooded with water for 3-4 hours prior to the placement of Congrout GP Immediately before the grout is placed all free water should be released from the area to be grouted. There should be NO standing water present when the grout is placed.
MIXING
Congrout GP should be mixed using a suitable mixer. For flowable consistency use a hand drill and paddle with a speed of <400 R.P.M. For large works use a high shear vane grout mixer. Drum mixers are not recommended. The entire contents of the bag should be added to the pre-measured (3.87-4.00 litres) water while mixing. DO NOT add more than the maximum water content.
APPLICATION
Ensure the substrate is prepared according to the manufactures recommendations. No free water should be present in the area to be grouted. Ensure that there is sufficient air release holes for entrained air to escape. Mortar should be continuously poured, from one side only, until the gap is completely filled. Maintain continuous head of grout when pouring.

HEALTH & SAFETY

Congrout GP is alkaline avoid contact with skin & eyes. Gloves, goggles and dust mask should be worn. Skin should be washed with water to remove & splashes in the eyes washed out with copious amounts of clean water and medical attention sought. Congrout GP is nonflammable.
