High Performance Hydrophobic And Crystallisation Waterproofing System
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.
Note: Cement refers to OPC. No cement replacement material shall be used in the concrete mix.

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.
Water absorption test in accordance to BS 1881 Part 122 as below;
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.
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.
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.
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.
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.
Estop’s Estopper Range PVC waterstop shall be provided between lifts of concrete and joint in floor bays.
