Estomix G15

High Performance Hydrophobic And Crystallisation Waterproofing System

 

 

Description

 

Estomix G15 is a dual purpose waterproofing system, when added to fresh concrete, reacts with products of the cement hydration process to produce a hydrophobic material and also initiates crystallisation process, which repels external water thus drastically reducing water absorption into the concrete. Crystallisation initiation process will be a long term effect due to its continuous process of crystal growth.

 

Estomix G15 has been tested by SIRIM Bhd, in accordance to BS 1881 Part 122:1983 on Water Absorption, BS 6920, on The Suitability for Contact with Drinking Water; certified by UNIKL for crystallisation process; tested by Testech Sdn Bhd in accordance to CRD-C 163-92 on Water Permeability Test (Triaxial Cell Method); tested by Setsco Sdn Bhd, in accordance to DIN 1048:Part 5 on Determination of Water Permeability and complied with the specification in this data sheet.

 

Uses

 

  • For complete and permanent waterproofing of mass and reinforced
  • Estomix G15 drastically reduces water absorption in structural and pre cast
  • It is recommended to be used in multi-storey basement, tunnel, water retaining/excluding structure, bridge deck, civil and building

 

Advantages

 

  • Chloride
  • Reduces surface
  • Minimizes cracking and plastic
  • Provides integral protection ensuring reduced permeability throughout the
  • Integral protection is maintained even if surface damage
  • Lower water cement ratio improves compressive strength at same
  • No protection required for floor and
  • Increase formation  of  crystal,  the  crystallisation  process is activated whenever moisture is present. Crystal growth continuously to block the path of moisture to prevent long term leaking.

Standards Compliance

Note: Cement refers to OPC. No cement replacement material shall be used in the concrete mix.

Typical Performance Examples

Estomix G15 meets the water absorption requirements of draft European standard EN 934-2.

Many variables in concreting materials and conditions can affect the use of an Estomix G15. Trials should be carried out using relevant materials and conditions in order to determine the optimum mix design and Estomix G15 dosage to meet specific requirements.

A typical performance example from evaluation studies of Estomix G15 is included on this data sheet. The values quoted are representative of results obtained and are provided as illustration of the performance.

Because of the variability of concreting material, the results should only be taken as typical of the performance to be expected. Results quoted are not necessarily directly comparable with result obtained elsewhere for Estomix G15.

Instruction for Use

Trial Mix

Trial Mix shall be conducted for concrete intended to utilize Estomix G15, to waterproof a particular concrete structure.

The targeted compressive strength of a particular grade of concrete shall be complied with BS 5328:1981, or its latest revision. The use of Estomix G15 shall be under adequate supervision. For further advice contact Estop Technical Department.

Typical Dosage

Estomix G15 may be dispersed to the gauging water at the rate of 1 litre per 100 kg of Portland cement.

Estomix G15 is also water reduction agent. Therefore the maximum free water cement ratio shall not be more than 0.50, before dosing of Estomix G15.

Slump of concrete before dosing shall be between 50mm – 70mm for normal concrete, and 60mm – 80mm for pump mix concrete, higher slump will be expected after dosing of Estomix G15.

The use of Estomix G15 at typical dosage will illustrate an excellent result on water absorption, as shown in Typical Performance Example.

Effects of Overdosing

An overdose of double the intended dose of Estomix may result in increased retardation and workability; hence reduce the short-term strength development. Long term strength is unlikely to be affected. Should segregation of concrete occur, due to excessive increase in workability, the concrete shall not be used.

Dispensing

The correct quantity of Estomix G15 should be measured by means of a recommended dispenser. The Estomix G15 should then be added to the concrete with the mixing water to obtain the best results. For further advice on equipment and tools contact Estop Technical Service Department.

Curing

Estocure spray applied curing membrane should be used.

Good concrete practice must be followed at all times. Well graded aggregates must be used and minimum cement content of 300kg/m3 is recommended.

Waterproofing to Concrete Joints

Estop’s Estopper Range PVC waterstop shall be provided between lifts of concrete and joint in floor bays.

Packing & Size

Estomix G15 210 litre drum

20 litre pail
