Overview

Located deep in the East Sussex countryside, the Hobbit House sits in beautiful countryside. The owners wanted to create unique luxury rental accommodation comprising two double en-suite bedrooms with open plan kitchen, dining and lounge area - a subterranean space which had the look and feel of a magical ‘Hobbit Home’ as if created by J. R. R. Tolkien himself.

Requirement

Delta Registered Installer, Renlon Limited was commissioned to create a waterproofing design for this newly constructed subterranean house.

Products used

  • Koster Polysil TG500
  • Koster NB4000
  • Koster Glass Fibre Mesh
  • Delta Terraxx

Methodology

The shell of the project was created using a Type B waterproof concrete system, followed by a secondary form of waterproofing incorporating the Delta Type A system. Initially the Type B concrete was primed with Koster Polysil TG 500, an anti-lime inhibitor. When new concrete is introduced to structures, there is a risk of excess free lime leaching out during the curing process, an anti-lime inhibitor reduces this risk. Once cured an application of Koster NB 4000 was applied as a primary waterproofer.

Koster NB 4000 is a Type A barrier waterproofing system, once applied but not dried Koster Glass Fibre Mesh was embedded in the first wet coat. Koster NB 4000 is a hybrid waterproofing product that combines the properties of a polymer modified bitumen thick film sealant and a flexible mineral waterproofing slurry. Once cured, an additional second coat of Koster NB 4000 was applied. Used as a green roof external drainage layer, Delta Terraxx was installed. Delta Terraxx is an extremely robust protection and drainage system that can be used in a range of applications for horizontal drainage which protects the primary Type A waterproofing system. Delta Terraxx has an adhesive tape manufactured on one side to overlap and join the membrane offering quick and easy install. Once the waterproofing system was successful applied and installed backfill was added.

Outcome

The Hobbit Home is completely protected against water ingress and the owners have a great addition to their portfolio, whilst rental occupants will be guaranteed a unique and magical stay. The work was finished well within time constraints and the client was extremely happy with the result.
