Core Services

Every basement waterproofing requirement. One approved contractor.

From new build Type B integral waterproofing through to remedial cavity drain systems on a failed existing basement — Vision SC specifies and installs the right solution.

01 / Type A

Type A — Barrier Protection

Tanking membranes and applied coatings bonded to the structure to resist water ingress. Appropriate for lower-risk situations with controlled water tables and sound substrates.

  • Cementitious tanking slurries
  • Sheet membrane systems
  • Liquid-applied coatings
  • External and internal application
02 / Type B

Type B — Structurally Integral

Waterproofing built into the concrete structure itself. Suitable for new build projects where the reinforced concrete shell forms the primary waterproofing barrier with appropriate admixtures and detailing.

  • Waterproofing concrete admixtures
  • Construction joint sealing systems
  • Hydrophilic waterstop installation
  • Sika and approved system application
03 / Type C

Type C — Drained Protection

Cavity drain membrane systems that manage water rather than resist it. The most reliable approach for remedial waterproofing and situations where water pressure or substrate condition is uncertain.

  • Newton cavity drain membranes
  • Sump pump installation & maintenance
  • Perimeter drainage channels
  • Monitoring & service access
04 / Remedial

Remedial Basement Waterproofing

Failed, inadequate or never-installed basement waterproofing rectified. We survey the existing situation, identify the cause of failure and specify the appropriate remedial system.

  • Failed tanking replacement
  • Remedial cavity drain installation
  • Crack injection & leak sealing
  • Root cause analysis report
05 / Conversion

Basement Conversion Waterproofing

Waterproofing design and installation for basement conversions in residential and commercial properties. Specification prepared to BS 8102 with appropriate system grade for intended use.

  • BS 8102 Grade 1–3 specification
  • Combined Type A & C systems
  • Newton and Sika system install
  • Structural opening waterproofing
06 / Tanking

Liquid Waterproofing & Tanking

Cold-applied liquid membrane systems for basements, plant rooms, lift pits and below-ground structures. Kemper System approved applicators for seamless fully-bonded membrane application.

  • Kemper System cold-applied membranes
  • Fully seamless — no joints or laps
  • Complex geometry & penetration detailing
  • Approved-contractor warranty available
Approved Systems

Approved installers for the systems specifiers choose.

Vision SC are approved installers for Newton Waterproofing, Sika and Kemper System — the three manufacturers most frequently specified on basement waterproofing projects in London and the South East.

Newton Waterproofing

Newton Cavity Drain Systems

  • Newton 508 & 520 cavity drain membranes
  • Newton NB sump and pump systems
  • Newton perimeter drainage channels
  • Approved-installer warranty available
  • Suitable for all grades of use — BS 8102 compliant
Kemper System

Kemper System's cold-applied liquid waterproofing membranes are ideal for below-ground structures requiring a seamless, fully-bonded waterproofing solution — particularly where complex geometry, penetrations or detailing make sheet membranes impractical.

  • Seamless fully-bonded membrane — no joints
  • Cold-applied — no hot works on site
  • Excellent detailing around penetrations
  • Approved-contractor warranty available
  • Suitable for lift pits, plant rooms, basements and vaults

Why Vision SC

Specialist depth. No guesswork on your project.

Basement waterproofing failure is expensive and disruptive to put right. We survey correctly, specify the right system for the conditions, and install it as the manufacturer intends.

01

Approved Installer Status

Newton, Sika and Kemper System approved installers — all operatives trained to manufacturer standards. Approved-installer warranties available on qualifying projects, backed at the manufacturer level.

02

BS 8102 Compliant Design

Every specification is designed to BS 8102 — the British Standard for protection of below-ground structures. We specify the right system grade for the intended use, not the cheapest option.

03

System-Agnostic Advice

We're approved for multiple systems, which means we recommend the right product for the conditions — not the one we're trying to sell. Type A, B, C or combined: we specify what works.

04

Remedial Expertise

Failed basement waterproofing is a specialism of its own. We diagnose the cause, not just the symptom, and specify a remedial solution that addresses the actual failure mechanism.

Common Questions

Questions we get asked about basement waterproofing.

Straight answers from a specialist contractor — not a sales team.

What types of basement waterproofing do you install?
Vision SC install all three BS 8102 waterproofing system types: Type A (barrier protection — tanking membranes and coatings), Type B (structurally integral waterproofing), and Type C (drained protection — cavity drain membrane systems). We recommend the right system or combination based on site conditions, groundwater pressure and intended use.
Are you approved installers for Newton, Sika and Kemper System?
Yes. Vision SC are approved installers for Newton Waterproofing cavity drain systems, Sika structural waterproofing products, and Kemper System cold-applied liquid membranes. We work to manufacturer specification on every project, with approved-installer warranties available.
Do you carry out basement waterproofing surveys?
Yes. We carry out detailed basement waterproofing surveys including visual inspection, ground condition assessment, existing structure review and review of any available drawings. From this we produce a written specification recommending the appropriate system type and a full cost plan. Surveys are available at no charge for qualifying projects.
Can you carry out remedial waterproofing on an existing failed basement?
Yes — remedial waterproofing is one of our core service areas. Whether the original waterproofing has failed, was never installed correctly, or simply wasn't appropriate for the conditions, we survey the existing situation and specify a remedial solution. Cavity drain systems are often the most reliable remedial approach as they manage water rather than trying to resist it.
Do you work on residential and commercial basement waterproofing projects?
Yes. We work across residential, commercial, retail, hospitality, public sector and infrastructure basement waterproofing projects. Projects range from single residential basement conversions through to large commercial undercroft and multi-level basement structures.
Where do you carry out basement waterproofing work?
Vision SC carry out basement waterproofing across London and the South East as a priority, and operate UK-wide from our base in West Thurrock, Essex. We regularly work in London, the Home Counties, Essex, Kent, and across England for commercial and public sector clients.
