DerinFiber PP – Fiber Reinforced Waterproofing

DerinFiber PP is a high-performance, fiber-reinforced waterproofing solution designed for enhanced durability and flexibility. Its advanced formula improves the tensile strength of concrete, forming a reinforced protective layer that effectively prevents water ingress and structural deterioration.

Key Features:

  • Fiber-reinforced for superior strength and crack resistance
  • Exceptional adhesion to a wide range of surfaces
  • Ideal for water tanks, terraces, basements, and industrial structures
  • Resists thermal expansion and contraction, ensuring long-term durability

Perfect for both residential and commercial applications, DerinFiber PP provides lasting waterproofing

  • To improve the durability of cementitious screeds and toppings by inhibiting the formation of small cracks, which occur because of plastic shrinkage and settlement due to premature drying.
  • Durability is further enhanced due to increased residual strength, resulting in improved abrasion, impact and spalling resistance
  • Even distribution throughout the mix is due to Fibers being coated with a special dispersing agent. Improves Fiber bond and eliminates the requirement for shrinkage control wire mesh reinforcement.
  • Can be used for internal & external plaster, concrete repairs, precast concrete railway sleepers etc.
  • Inhibits plastic shrinkage and settlement cracking
  • Eliminates shrinkage control wire reinforcement
  • Cost effective compared with wire reinforcement
  • Specially pre-bagged to ensure correct dosing
  • Improved abrasion, frost and impact resistance (good drop hammer results)
  • Over 300 million Fibers per m3 of screed
  • Controlled dispersion throughout the mix
  • Reduced permeability and water absorption
  • Reduced segregation and bleeding
  • Improves surface Finishing
  • Alkali resistant and will not corrode.
  • Can be used with all types of cement.
  • Used as a secondary reinforcement in concrete
  • Improves tensile and compressive strength

Instruction for use

DERINFIBER PP cannot be used as a replacement for structural steel reinforcement

Approx. 1 kg of 12 mm DERINFIBER PP per cubic meter
of screed or topping.
– 75 g bag to 25 kg of cement
– 150 g bag to 50 kg of cement
– 500 g bag to a 1 tonne batch of ready mixed screed

When site mixing screeds, the fibers should be added immediately following the aggregates, cement and half water whilst the mixer is turning. The balance of the water to achieve required workability is then added and mixing continued to ensure DERINFIBER PP are thoroughly dispersed. Minimum total mixing time is 5 minutes. When plant batching screeds, in a forced action mortar mixer, the fibers should be added to the mixer as the First ingredient, followed by the other constituents.

Screeds or toppings containing DERINFIBER PP may have an apparent increase in cohesiveness. It is important that additional water is not added. Fiber dosed mixes may be hand tamped or rolled to provide the necessary compaction.

Screeds or toppings containing DERINFIBER PP may be power floated or hand steel trowelled to provide a smooth and fiber-free surface appearance.

Normal good curing practices for conventional screeds or toppings must be strictly followed.

  • Packing : 125 gms., 500 gms. & 1 kg.
  • Dosage : 125 gms. / 50 kg. bag of cement

The shelf life of Derinfibre PP is 18 months from the date of manufacture when kept at a temperature between 5°C to 45°C and stored in the original, unopened bags. All materials must be stored under cover in such a way that they avoid damage (preferably on pallets) and are protected from excessive heat and moisture. Do not freeze.

DERIN CHEMICALS & PAINTS is a firm of Assessed Capability. The company’s quality system conforms to ISO 9001:2008.

Health & Safety: DERINFIBER PP is no-toxic and non-flammable. Avoid inhalation of dust during mixing and wear safety glasses, dust mask and gloves. If skin contact occurs wash thoroughly with clean water. Should eye contact occur rinse immediately with plenty of clean water and seek
medical advice. Full health and safety data are given in Product Safety Data Sheet.
