Fosroc Nitofill TH is developed for the injection of cracks between 0.5mm and 9 mm wide in concrete and masonry, and has been specially formulated to minimise the drainage of resin from cracks which are incompletely sealed.
- A two pack thixotropic epoxy resin product for the repair of cracked concrete and masonry by the injection process
- Thixotropic: Permits injection of open-ended crack
Also available: Fosroc Nitofill LV, a low viscocity epoxy resin product permiting maximum resin penetration.

Features & Benefits
- Thixotropic: Permits injection of open-ended cracks
- Adhesion: Achieves high strength bond to dry or wet concrete
- Minimum creep: Material designed for low creep
- Non-shrink: No loss of bond or surface contact
- High strength: High compressive, tensile and flexural strengths
- Chemical resistance: Withstands most chemicals, acids and alkalis, also fresh/sea water and frost, oil, grease and fats
- Conforms to BS EN 1504 Part 5
Application Notes
- Mechanical mixing is preferable (i.e. Jiffy mixer in slow speed drill). Pour all the contents of Hardener pack into Base container. Mix for 2 minutes or more until homogeneous
- The product may be pumped into place using a standard ‘grease gun’ technique
- For small-scale jobs a Fosroc ‘G’ Gun may be used
- Where greater rates of injection are required a hand pump may be used, or bulk supplies of Nitofill LV and Nitofill TH may be used with twin metering/mixing machines
- 12 to 18 hours after injection, the injection tubes should be broken off and any damage made good using Nitokit Surface Sealant
- Tools and application equipment should be cleaned using Fosroc Solvent 102 immediately after use. Cured material can only be removed mechanically. Spillages should be absorbed with sand or sawdust and disposed of in accordance with local regulations
- Pot life: 40 minutes @ 10°C, 20 minutes @ 20°C, 10 minutes @ 30°C
- 1 litre units each consisting of base & hardener
Limitations
- During application, injection can be carried out without special precautions at ambient temperatures from 5°C to 25°C. Where ambient temperatures exceed 20°C note the pot life will be reduced. Cure temperatures below 15°C will result in slower strength build up; at 5°C cure will stop until the material warms
- In service, the cured grout is completely resistant to frost and extreme sub-zero temperatures, and is suitable for continuous use up to 35°C
- To eliminate risk of exotherm, this product should only be mixed when ready for use and then applied without delay. Any unused residue should be poured on to a disposable impervious surface to allow cure before disposal
