BKM HZ250 Pro Damp Proofing Injection

Professional Damp Proofing Solution for Rising& Penetrating Damp in Masonry

BKM HZ250 Pro is a high-performance damp proofing hydrophobic barrier designed to create effective horizontal damp proof courses (DPC) and surface barriers in mineral masonry. Engineered to stop rising damp and capillary moisture, it provides a long-lasting solution for protecting walls from water ingress and structural damage.

Used across residential, commercial, and heritage buildings, BKM HZ250 Pro delivers reliable results while maintaining the natural breathability of masonry walls.

How BKM HZ250 Pro Works

Unlike traditional damp proofing systems, BKM HZ250 Pro penetrates deep into the capillary structure of brick, stone, and mineral masonry, reducing moisture movement from within.

  • Prevents capillary rising damp

  • Stops horizontal, penetrating and lateral moisture penetration

  • Can be retrofitted to deal with awkward spaces

  • Allows walls to dry naturally over time

This advanced system supports long-term moisture control without compromising the building fabric.

  • BKM HZ250 Pro uses “breathable waterproofing” technology, meaning:

    • ✅ No vapour-tight barrier

    • ✅ Maintains natural vapour permeability

    • ✅ Prevents trapped moisture and condensation build-up

    • ✅ Ideal for older and heritage properties

    This makes it the preferred choice where traditional impermeable systems could cause further damage.

  • Many damp proofing products introduce harmful salts into masonry. BKM HZ250 Pro is different:

    • Contains no hygroscopic salts

    • Prevents future salt contamination and staining

    • Protects the long-term integrity of walls

  • BKM HZ250 Pro is fully tested and certified to:

    WTA Guideline 4-10-15/D – a recognised European standard for rising damp treatment in masonry.

    This ensures proven performance, reliability, and suitability for professional damp remediation projects.

Applications of BKM HZ250 Pro

BKM HZ250 Pro is ideal for:

  • ✅ Rising damp treatment in brick and stone walls

  • ✅ Residential damp proofing projects

  • ✅ Commercial and industrial buildings

  • ✅ Heritage and listed properties

  • ✅ Structural waterproofing and moisture control

Professional Installation Matters

At Heritage & Modern Damp proofing Solutions Ltd., we use BKM HZ250 Pro as part of a comprehensive damp proofing strategy.

We always recommend addressing the root cause of moisture alongside injection treatment to deliver a long-term, effective solution.

Frequently Asked Questions (FAQs)

What is BKM HZ250 Pro used for?

BKM HZ250 Pro is used to treat rising damp in masonry walls by creating a horizontal moisture barrier that stops capillary water movement.

Is BKM HZ250 Pro suitable for older properties?

Yes, it is ideal for heritage and period properties because it allows walls to remain breathable while preventing moisture ingress.

How long does damp proof injection last?

When installed correctly, systems like BKM HZ250 Pro provide long-term protection, often lasting decades.

Does it block moisture completely?

No. It reduces moisture movement while allowing water vapour to escape, helping walls dry naturally.

Do I still need to fix the source of damp?

Yes. Injection systems work best when combined with resolving the root cause of moisture, such as drainage or ventilation issues that will be identified during our comprehensive survey.
