Liquid Waterproofing

As you are obviously aware, water sealing is a field of vast and varied requirements. However, we pride ourselves as specialists in the control of free flowing or capillary migration, hydrostatic and latent movement of water.

Liquid Waterproofing and Sealing operates as a specialist company and is able to deal with all civil engineering and mining water leakages of all types derived from a uniquely experienced background of the toughest engineering environments.

We have an experienced engineering team with an exceptional level of expertise in concrete technology and construction, water control, support and stabilisation techniques.

By retaining a specialist approach, the company is able to deliver on time and within budget and has strict quality controls over all aspects of the operations.

All our components are tried and tested under extreme pressures with high volume water flow. These very high pressures are only limited by the grout pumps itself. Pressures of up to 50 Bar can easily be achieved.

We’ve successfully sealed fissures with water flow rates of more than 1.6 million litres of water per hour.

Like any superior system, P100 grout treatment is no doubt very cost effective. The cost compares favourably with the cost of alternative sealing methods.

The differences are that P100 requires less time and that much fines passages can be penetrated and sealed.

The positive sealing effect of P100 makes it possible for experienced personnel to predict the likely success that can be achieved after careful inspection and evaluation of each watermark problem. Contracts for water sealing can therefore be negotiated based on the success rate achieved.

Patented grouting systems
Professionally trained and competent staff.
Experienced grouting personnel.
The expertise to study geotechnical reports and design a pre-grout program to deal with an area prior to excavation, for shafts or decline locations, in order to minimize or eliminate water ingress at the time of construction.
Research and development of new sealing technologies continuously on trial in the wettest underground sites in the world.
High pressure grouting equipment and supplies.

Mainly used in the sealing of porous areas in concrete and rock strata.
Waterproofing of concrete type structures like tunnels, mine shaft linings and dam walls.

PRE-GROUTING
Pre-excavation of formations.
Hard Rock. Soft Rock. Sandstone Sand.
REMEDIAL GROUTING
Joints.
Lined Structures.
Leaking Formations.
Aquifers.
REACTIVE GROUTING
Stop inflows at once.
CURTAIN GROUTING
Preventative grouting.
Isolating areas to be kept dry.

Particle size less than 1 Micron - extremely permeating
Saves cost on drilling due to the remarkable spread of grout - even at low injection pressure
Does not wash out during grouting - seals leaks of 200 L/sec successfully
Exceptional performance under high pressure - successfully sealed static head of 20,000 kPa
Curing chemically controlled from several seconds to 48 hours
Seals saline and hypersaline water effectively
Performs well when pre-grouting shafts, declines and pilot holes due to extreme penetrability
Remains flexible once solidified and will not re-leak with ground movement (400% elasticity).
Durable - no leak recurred during 3 decades of grout history
Reaction is not exothermic - no expansion effect
Environmentally friendly - non hazardous
