HA Soil AF
Next generation, phthalate-free, one-component, high performance, low viscosity, hydrophobic, hydro-active, rigid polyurethane injection grout used to increase the load bearing capacity of loose soil
Product Description
In its uncured form, HA Soil AF is a dark brown, non-flammable, low viscous liquid without phthalate plasticisers. When HA Soil AF comes into contact with water, the grout expands and quickly (depending on temperature and the amount of HA Soil Cat AF catalyst used) cures to a rigid polyurethane foam.
Field of Application
- High strength soil stabilisation.
- High strength anchoring in wet or dry conditions.
- Pre-injections for waterproofing and consolidation in front of TBM, drill-and-Blast and NATM.
- Combi-Grouting in combination with cement or micro-fine cements.
- Tie-back and screw rod anchoring in wet or dry conditions.
- Curtain injections and chemical containment.
- Soil stabilisation around sewer lines.
- Filling large voids in rock fissures, crushed faults, gravel layers in wet or dry conditions using special techniques and/or filled resins.
For additional information on areas of doubt, please consult your local GCP representative.
Product Advantages
- ADR free transport.
- Next generation resin with improved performance.
- Improved cell structure of the cured compound resulting in better mechanical properties and durability.
- Phthalate-free resins, REACH compliant.
- Improved performance at temperatures below 5°C, no crystallisation of HA Soil Cat AF.
- Can be injected into silty sand with a coefficient of 10-6 m/s (or 15% of the particle size 0.074mm).
- Non-flammable, solvent- free.
- User friendly: one-component product.
- Controllable reaction times: by using catalyst curing times can be reduced.
- Cured compound is resistant to most organic solvents, mild acids, alkalis and micro-organisms (*).
(*) For chemical resistances please contact your GCP representative.
Application
HA Soil AF is used for stabilising loose soils or to increase the load bearing capacity of these soils.
1. Soil investigation
- To determine the suitability of the soil to be grouted, the soil is to be in accordance with local guidelines and regulations. A full study of the situation and the characteristics of the soil has to be made prior to commencing the injections.
2. General considerations
- It is recommended that the soil injection is carried out at the lowest possible pressure. The required pressure is influenced by the load pressure on the soil, permeability, injection speed, resin characteristics, etc.
- The flow rate required for a successful injection needs to be determined by trial injection on the site prior to the actual work.
- Spacing and depth of the injection points will be determined after studying the soil and application requirements.
3. Preliminary checks
Before installing the injection tubes into the soil, check the following:
- Investigate the presence of municipal underground utilities such as water or power supply, sewers, underground water pockets, etc.
- Investigate the presence and behaviour of the ground water.
- Investigate the characteristics of the soil and the geological composition of the site.
- Test the permeability of the soil for water and resin.
4. Resin preparation
- Shake HA Soil Cat AF well before use.
- Mix the resin with the predetermined amount of HA Soil Cat AF catalyst using a slow speed mixer (400 to 600rpm). Shield the vessel with the premixed resin from water ingress since this will cause a reaction in the vessel and pumping equipment.
5. Injection
- The injection procedure can be split up in 4 steps.
- Installing the injection tube (sleeve port pipe/strainer pipe) to the planned depth.
- Start the injection with the mixed material.
- Controlled withdrawal of the injection tube at predetermined depths and time intervals.
6. Cleaning
- When the injection is finished, clean all tools and equipment, which have been in contact with the resin with Washing Agent. This should be done within 30 minutes. Do not use solvents or other cleaning products since they give less positive results and can create hazardous situations.
- Products should be disposed off according to local legislation.
