Hatocot® (Roof dog house)

Product Series - Construction

Hatocot® (Roof dog house) Overview

The HATOCOT® is Japan’s No. 1 ready-to-assemble roof penetrations housing or “dog house” since 1987. Three main features of Hatocot®: 1. Easy and quick installation, 2. Easy access for maintenance, 3. Lightweight to lessen burden of building structure.
Conventionally, construction of a plumbing cover on a roof needs many complicated steps and long period of time; including: marking, form assembly, bar arrangement, concrete placement, form removal, waterproofing, and mortar finishing before laying roof slabs.

The ready-to-assemble HATOCOT® provide standardized dimensions and quality serves to shorten the planning and construction period, and contribute to reduction in waste material generated at construction sites.

Features of Hatocot® Roof Dog house

  • Greatly shortening the work period
    Use of a ready-to-assemble Hatocot unit eliminates many troublesome steps that are required in conventional methods. Surface protection by other members is not necessary, allowing work on waterproofing the roof and plumbing in the facilities to be started immediately after Hatocot installation.
  • Easy maintenance of plumbing and electrical equipment
    Plumbing requires periodic inspection and cleaning. Consisting of three-part configuration, the Hatocot can be easily maintained as the top lid is removable.
  • Suitable for Additions & Alterations (A&A) works and enlargement works that requires access through the roof slab
    When an extension is built onto an existing building, the roof is often used as a work space. Such work requires access through the roof slab, causing much trouble for waterproofing and other tasks. Use of the Hatocot will ensure economical, high-quality construction.
  • Constructed of FRC (the top body is made of ZAM-steel)
    Special FRC (fiber reinforced concrete) was developed for the Hatocot to resist harsh environmental conditions on roofs. Compared to conventional concrete, it is highly resistant to freezing and thawing, is durable and strong against water absorption, and is lightweight.
