Roofs and large balconies expand and contract significantly under the sun, causing rigid waterproofing to crack and fail. Sika Top Seal 109 is a highly elastic, two-part cementitious coating designed specifically to move with your building while maintaining a flawless, watertight seal.
In regions with heavy rainfall, a cracked roof means immediate interior damage. Sika Top Seal 109 utilizes a high ratio of advanced liquid polymers to provide unmatched crack-bridging capabilities. Choosing this elastic barrier ensures that even as your structure subtly shifts, your waterproofing defense remains completely unbroken.
