Waterproofing Integral Additive

Integral waterproofing additive for concrete and mortar to reduce capillary water absorption and permeability, supporting durable moisture resistance from within the cementitious matrix.

Grades: hydrophobic or reactive/crystalline (by inquiry)
Documentation: SDS / COA / TDS (as available) on request
Packaging: drums / IBC / bags / supersacks (grade dependent)

Project note: Waterproofing performance depends on mix design, curing, and detailing. Share your exposure conditions (groundwater/hydrostatic pressure, freeze-thaw, chloride exposure) so we can align the appropriate grade.

Product overview

Waterproofing integral additives are introduced directly into the cementitious mix to reduce water ingress pathways. Depending on grade, performance is achieved by hydrophobic pore-lining (repels water and reduces capillary uptake) and/or reactive/crystalline mechanisms (reduces capillary continuity by forming insoluble structures in pores). Integral waterproofing is widely used where long-term moisture resistance is needed without relying solely on surface-applied systems.

Primary benefit

Reduced capillary absorption and permeability, improving resistance to dampness and water ingress.

Durability support

Helps limit moisture-driven deterioration (efflorescence risk, freeze-thaw scaling, reinforcement corrosion drivers).

Where it fits

Concrete, mortar, screeds, renders, plaster, precast products, and cementitious repair mortars.

If your project has a specified test method (e.g., water absorption, depth of penetration, permeability class), include it in the RFQ for grade matching.

Applications

Typical usage patterns. Tell us your mix design, production method, and exposure constraints and we’ll align the right grade and documentation.

  • Ready-mix and site-mixed concrete (integral damp-proofing)
  • Precast concrete elements (segments, pipes, pits, panels)
  • Mortars, plasters, renders, screeds (reduced water uptake)
  • Cementitious repair mortars and grout systems
  • Low-permeability mixes for durable infrastructure

Concrete & structural

Foundations, retaining walls, basement slabs, water-resistant structural elements.

Precast & manufactured

Pipes, manholes, panels, blocks and pavers where water absorption limits are specified.

Mortar systems

Renders, plaster, repair mortars and screeds for damp-resistance and durability support.

Performance & design guidance

Integral waterproofing works best as part of a complete durability strategy (mix design + curing + detailing).

Ask for grade selection

Reduced permeability

Targets capillary water movement by reducing pore connectivity and/or lining pores for lower absorption.

Durability support

Lower moisture ingress can reduce drivers for corrosion and freeze-thaw deterioration in many exposures.

Finish & aesthetics

Can help reduce efflorescence risk by limiting water transport through cementitious layers (project dependent).

Typical dosage (starting range)

Dosage is grade-specific and depends on cement content and exposure. As a general starting point for many integral waterproofing additives:

  • Concrete: typically 0.2–1.0% by weight of cement (grade dependent)
  • Mortars/renders: typically 0.5–2.0% by weight of cement (grade dependent)
  • Precast: matched to absorption/permeability targets and cycle conditions

Final dosage should be confirmed by trials against your target test method and mix design.

Typical specifications & formats

Values depend on grade and customer requirements. Confirm details on quotation (TDS/COA as available).

Quality & documentation

Chemistry options

Hydrophobic pore-lining or reactive/crystalline (selected by application)

Form

Powder or liquid (grade dependent)

Appearance

White/grey powder or clear/amber liquid (typical; confirm on offer)

Chloride content

Low / non-chloride grades available (request if reinforced concrete)

Alkali contribution

Grade dependent; confirm if you have ASR-related requirements

Packaging

Bags / supersacks (powder) • Drums / IBC (liquid) • Bulk (by lane)

Documentation

SDS / COA; TDS and compliance statements on request (availability varies)

Shelf life

Grade dependent (typically 12–24 months when stored correctly)

Notes

Performance depends on curing, compaction, and crack control—request best-practice guidance if needed.

Specifications may vary depending on batch, origin, and packaging selection. Provide your acceptance criteria (e.g., max chloride, form, density, setting impact) for a tighter offer.

Handling, storage & dosing

General guidance—follow SDS and plant procedures. Dosing method depends on powder vs liquid grade.

Request documentation

Powder grades

Typically added with cement or aggregates during batching. Avoid moisture exposure; ensure uniform dispersion.

Liquid grades

Typically dosed via admixture dispenser into mix water or mixer. Avoid overdosing; verify slump and air.

Storage

Keep sealed in original packaging, protected from moisture and extreme temperatures. Shelf life varies by grade.

For waterproofing performance, ensure proper compaction and curing and maintain crack control practices—integral additives reduce permeability but do not “seal” large cracks without appropriate design and detailing.

Request a quotation

Share your mix design and waterproofing target and we’ll propose a suitable chemistry option, dosage guidance, packaging, and documentation set. If you are matching an existing product, include the benchmark name or key properties.

Fast matching

Exposure + target test method = correct grade recommendation and documentation.

Commercial clarity

Volume + destination = best packaging and lead-time routing through the right lane.

Compliance

Include any chloride limits, non-corrosive requirements, and project specifications in your RFQ.

FAQ

Common questions from contractors, precast plants, and procurement teams.

Request quotation

Hydrophobic vs crystalline—what’s the difference?

Hydrophobic grades reduce water uptake by repelling water in capillaries; reactive/crystalline grades reduce capillary continuity. Selection depends on exposure and target testing.

Does it impact slump or set time?

It can, depending on chemistry and dosage. We recommend trials to confirm workability, set, and strength development against your baseline mix.

Can it be used with PCE superplasticizers?

Often yes, but compatibility should be checked for your full admixture package (PCE, air-entrainer, accelerator, etc.). Share your admixture list in the RFQ.

Does it replace membranes?

Integral waterproofing reduces permeability, but membranes/coatings may still be required for severe hydrostatic pressure or detailing-critical assemblies. Many projects use both.

What packaging is available?

Powders are typically supplied in bags or big bags; liquids in drums or IBCs. Availability depends on grade and supply lane.

What documents can you provide?

SDS and COA are standard on request. TDS and compliance statements may be available depending on grade and origin—request them during RFQ.
