Analysis of Waterproofing Defects and Technology Development for Car Parking Roofs: Lithuanian Case

Abstract

This work presents the analysis of installation options of exploitable car park roofs offered by the designers, material manufacturers and suppliers and introduces the Lithuanian legislation with the requirements for this type of roofing. Reasons of the most frequently occurring defects have been examined and several options for correcting defects have been provided. The most cost-effective option for correcting the defect in question has been chosen. Practical measures for increasing the reliability of exploitable car park roofs have been proposed. The analysis has shown that at a minimum slope reliability of the exploitable roof coated with roller heat-welded materials is not guaranteed. The authors propose to tighten the requirements on car park roofing.

Selecting the most effective alternative of waterproofing membranes for multifunctional inverted flat roofs

“…Now, cold, liquid, spread over or self-adhesive elastomeric products, which differ in chemical composition and the methods of their application, are available on the market. The problems associated with damp-proof roofing may be caused by the changes in atmospheric conditions and decrease in the quality of the performed works (roof base preparation, in particular) (Ustinovichius et al 2012).…”

Reconstruction of Khrushev’s Buildings of Series 1-528

“…They will be available for young families and the elderly. Each parking space has a separate entrance and exit to the landing [12].…”

“…Parking spaces for thirteen cars are also designed. Total parking area is 226.3 m 2 .Each parking space has a separate entrance and exit to the landing[12].Facades of Khrushev's building changes during reconstruction. Construction of additional walls gives the building an additional plasticity.…”
