Product Information
Shelf Life: 6 months from date of production.
Storage Conditions: Store properly in dry conditions in undamaged and unopened original sealed packing.
Chemical Base: Cement, selected fillers and aggregates, special additives.
Consumption: Depends on the substrate roughness and thickness of layer applied. As a guide, 1 bag yields approximately 13.0 litres of mortar.
Layer Thickness: 10mm min / 200mm max.
Substrate Preparation
Watertight Concrete
- Surfaces must be sound, thoroughly clean, free from ice, oils, grease, standing water and any loose or friable particles and any other surface contaminants.
Sealing around Pipes
- 2 x bands of Sikaswell A2005 adhered with Sikaswell S2 around the outside of pipe prior to grouting. (Minimum cover to A2005 is 75mm).
Shutter/Formwork
- Where formwork is to be used, all formwork should be of adequate strength, treated with release agent and sealed to prevent leakage.
- Sealing can be achieved by using Sikaflex® -11FC+ sealant beneath or around formwork and between joints.
- Ensure formwork includes outlets for extraction of the pre-soaking water.
- A header box/hopper should be constructed on one side of the formwork so that a grout head of 150-200 mm can be maintained during the grouting operation.
SUBSTRATE PREPARATION
- The substrate should be prepared by suitable mechanical preparation techniques such as high pressure water jetting, breakers, blastcleaning, scabblers, etc.
- The concrete substrates should be pre-soaked with clean water continuously for 2-6 hours to ensure a saturated surface dry condition throughout the operation.
- Immediately before pouring grout, remove all excess or standing water from within any formwork, cavities or pockets.
MIXING
- Place the water into a forced action grout mixer or in a clean drum.
- Slowly add complete bag of Sika MonoTop®-130 Seal into the water and continuously mix for 3 minutes in mixer to achieve a uniform and lump free consistency.
- Alternatively use a slow speed drill (200- 500 rpm) and spiral paddle mixer.
Application
- Pour the mixed grout into the header box/hopper ensuring continuous grout flow during the complete grouting operation to avoid trapping air.
- Use steel banding or chains to assist flow where necessary.
- For large volume placement, grout pumps are recommended.
- For cold weather working consider using warm water to assist with achieving strength gain & other physical properties.
Curing Treatment
- After the grout has initially hardened, remove formwork and trim edges while concrete is ‘green’.
- Protect the fresh material from premature drying using appropriate curing method e.g. curing compound such as Sikafloor® ProSeal, moist geo-textile membrane, hessian, polythene sheet etc.
- In cold weather apply heat blankets to maintain a constant temperature.
Cleaning Of Tools
- Clean all tools and application equipment with water immediately after use.
- Hardened/cured material can only be mechanically removed.
